Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470696, here are decompositions:

43 + 31470653 = 31470696
67 + 31470629 = 31470696
73 + 31470623 = 31470696
139 + 31470557 = 31470696
149 + 31470547 = 31470696
227 + 31470469 = 31470696
317 + 31470379 = 31470696
337 + 31470359 = 31470696

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.52.104.

Address: 1.224.52.104
Class: public
IPv4-mapped IPv6: ::ffff:1.224.52.104

Public, routable address (assignable to a host on the internet).

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
